摘要
根据区域网平差的基本原理,提出了不同类型卫星遥感影像联合区域网平差的方法,建立了光束法联合区域网平差模型,对误差方程式的建立、权矩阵的计算、多片前方交会模型的建立以及平差计算过程的设计等关键问题进行了研究,并通过两组实验验证了平差模型的有效性,分析了影像组合形式以及控制点的分布、数量、精度对平差结果的影响,最后总结了多源遥感影像联合区域网平差的特点以及应用前景.
The idea of the combined block adjustment of variant satellite remote sensing images was proposed and the combined bundle block adjustment model was constructed. Some key issues were studied, such as construction of observation equation, computation of weight matrix, space intersection with multiimage and the frame of computation process. The validity of the model was confirmed by two experiments. The influences of the image combined form, and distribution, amount and precision of ground control points on the adjustment result were analyzed. At last, the characteristics and prospect of the combined block adjustment were summarized.
